To your Accountant.
A change over to a SIP service equals reduction in ISDN line charges, substituted with a lower cost IP circuit and usually reduced calling costs.
To your IT Guy.
SIP is a protocol used to connect phones or video devices whether that be internally or via a SIP service provider like SIPcity.
To your Business.
SIP means reduced costs with productivity gains via access to features like Video, Conferencing, IVR, Agent and Queuing and softphones for worker mobility.
More and more companies are responding to developments in the enterprise communications market and are migrating to SIP trunking services like SIP trunking provider SIPcity. They are realising average cost savings of around 33 percent.
Reduced costs are one thing and one not to be sneezed at. There are addition enterprise benefits like high-definition voice and operational benefits such as disaster recovery and high availability.
For companies with a distributed business with multiple locations SIP trunking is an attractive solution. When a new branch location is opened, you simply add the branch to your LAN and route more bandwidth to that location to add the voice services.
Another key benefit to SIP trunking is that a business can buy only the capacity it needs. This means spending less money on telephony whilst getting the full end-to-end IP experience and quality. VoIP quality can be better than TDM when it is optimized to the network.
Going forward, the enterprise communications future is going to be an all-IP environment. The end of the public telephone network is in sight. SIP Trunking will be an integral part of the IP environment – the business-to-business and business-to-consumer calling paths.
As a term is an often misused and easily confused phrase. Technically, a SIP trunk or (SIP Peer) refers to two direct static IP connections between the customer’s router and SIPcity. Alternately, customers connecting individual handsets to our cloud hosted voice platform will use Registration. They simply enter a username, password and SIPcity proxy address (eg, call.sipcity.com.au) on each handset. While there are exceptions to SIP Peering vs. Registration, this is the general principle.
What is a SIP Trunk?
In non-technical terms, a SIP Trunk is a virtual connection over the public internet or a virtual private network (VPN) that connects switching equipment. This is the basis of VoIP telephony.
In technical terms SIP Trunking is a Voice over Internet Protocol (VoIP) and streaming media service based on the Session Initiation Protocol (SIP). This is used to deliver telephony services to customers who have SIP-based IP-PBX facilities.
